L l. improvements in table Elevators; i

7 following is .n of the mti u, wagon dumps.

The ob ect of the invention is to provide en elevator t5 peculiar @rrengenient well adapted lor lnunlhng ear corn, shelled corn and the small grains.

, hject also is to provide e simple form elevator preferably occupying a vertical position and provided with peculiar means in e to its boot for permitting the clove rendilv enter said boot though the lul tel n uy be lull oi grain, even in th" form of ,orn n the A further object to provide for the boot of {L11 elevetor a shield behind and beneath which the empty buckets nuiy pass into the said. boot for gathering their lends.

Another object is to provide in on elevator pe ulinr dumping means at its top for auto nnitic-elly emptying its loaded buckets.

In the accompanying; drawings Figure l is vertical section of my elevator showing comeyer or drag in connection therewith in cross section and also showing pan-t ol :1 wan on-plutterin. Fig. 1 is it top view ol :1.

A indicates n. phitlorm for the wagon to be unloaded and to which is uttuohcd itt one side, in any suitable nniinner, an elevator hoot ii which curries the i'nembers or limbs end ll oi the elevator. in the elevator boot at E is a. shall provided with sprocket wheels the positions of \vlncl are indicated in broken lines in Figs. 1 mid 3 at if. These said wheels curry the elevator chains indicated at Q 'wh' are provided at intervals with buckets U. The said sprocket wheels F ere oi such a (lizunctel uS to centralize the cl sins within the portions or legs (l and l.) in the elevator so that the buckets run properly travel therelhrough. in the elevator boot and. forming the bottom therefor is it seniicylindrical member J, preferably of sheet metal, arranged conco'ntricnlly with the perimeters of the sproclwls and placed such a distance therefrom that the sides ol' the buckets G will drop thereupon so as to gnther the grain properly. (j'onccntric with the member or bottom 3 is n. shield or iljlltll'll also of sheet metal beneath which the buckets Til travel they enter the boot, the elevator member (7 being properly extended to meet said guard so that it closed passage extends down into the bottom ol the boot. The upper ends of the portions or legs C and l) of the elevator support two arched plutcs .l in suitable manner and each plate curries two sets of sprockets M N there being two ol' the 'l'ormcr above the lee ll nnd lwo ol' the latter above the limb i, Fig. l. it will be noted thnt there are two sprocket chains both oi which are shown in Figs. 2 end 2' and consequently there must he corresponding pairs of the wheels.

The buckets ll are carried and suspended between the chains and consequently they pass between the wheels M. and Bctween the wheels M and nrc idlers O and these idlcrs are so positioned that 21s the chain passes from tho uppor pcriplmry ol' the wheel M to said idler the bucket is tipped as shown in Fig. 1 so as to dolivcrits contents into it chute .1 held in any suitable manner between the elevator limbs and l). 'lhe buckets on being emptied puss the wheels N and down into the elovutor. The idlers are preferably vertically adjustable so that the tension oi the c ruins may be varied,

EXiw-lltlllil); across the platform Iris the conveyor or drug Q usually employed on wagon dumps and which is provided with slntl'ts it for (worrying; the usuul interior sprockets one of which is indicutod at S in broken lines in Fig. 3. The shalt it nearest the elevator l'orms 2t pivot tor the conveyor and is held in suitable henrings 'l uttzu-hed to said elevator. This conveyor extends between the legs ol' the elevator and lischarges the grain into the boot between Sitltl lens. This arrangement zuhnits oi nntking the boot substantially longer in horizontal ineasuiement than the total width of the elevator itself.

Furthermore, it admits oi rais mg the conveyor and foldinilit and the elevator in compact form for s ing or storin' purposes. In addition to t is the chute P eing short and having a position bietweenthe legs'O and D above in theseme vertics-l plane with the conveyor occupies but vided with a beveled gear wheel W Ines ing with and drivin the shaft E ol t ing shown in broken lines iIiFig. 2. On said a similar beveled ear X on shaft V is a s rocket wheel 2 for driving a veyer Q by sing pivotal on the elevatorcan' c said conveyor.

sprocket whee 3 on one of the shafts R of t 1 'e' conveyor by means of a sprocket chains.

Motion im arted in .the pro er direction to the shaft the proper direction While at the same time l'llOlJlO'l is imparted to thechain .of-the convefier so that grairidumped "into the latter W1 be discharged into the elevator boot. In falling into the boot'the shield prevents. the grain obstructing-the ath of the buckets where they enter the e evator boot. so that said buckets can pass downw-erd into the boot between said shield K and the bottom J- and as they emerge from heneathseid shield the rain is scooped up. The conbe read ly tilted onend out of the way to ermit the loaded wagon to pass upon the plat form inposition for deliveringits load into am'notconfined, of course to using the pl tform A, I merely havin shown this because it is used many lei-inset ,wegon dumps. It is'onlynecessar to provide such a support es'will properly iold'theelevator in position for doing its work and the wagon of'the invention. 1
